Currently, we can go use Firefox or Joe's homemade browser to to back the features that Chrome removes, such as the ability for an ad-blocker to access and remove content. But we've already seen just last month [1] that Google actively prevents Firefox from using some features of Google products (need to find the HN link). Thus Google as a content provider can easily steep people into using the Google web browser.
This is really starting to smell similar to the Microsoft - IE debacle all over again.
